London, Sep 24 : Jailed radical Islamic preacher Abu Hamza’s poem glorifying martyrdom has suddenly appeared on YouTube.

Hamza, serving seven years in London’s top-security Belmarsh Prison, delivers nine verses in Arabic under the title “Death, eagerly for the sake of Allah.”

He praises the “spirit of the martyr” and asks for jihad fighters to be given God’s mercy, The Sun reported.

Last night a senior MP demanded to know how the poem came to be on YouTube - a favourite of millions of web fans.

The verses, used as the soundtrack to an al-Qaeda style video lasting three-and-a-half minutes, has also been posted on a site run by a London-based Egyptian exile listed in the US as a “global terrorist”.

A photo of the hook-handed cleric was displayed with an announcement that the recording is by “Sheik Abu Hamza Al Masri from Belmarsh Prison in Britain”.

The website also features images of Osama Bin Laden and the late leader of al-Qaeda in Iraq, Abu Musab al-Zarqawi, who murdered British hostage Ken Bigley.

The tape is the first time a new recording of Hamza has been issued since he was held four years ago for soliciting murder. But a written interview with him appeared on the web three months ago.

Last night Tory MP Patrick Mercer demanded a probe into the poem by Home Secretary Jacqui Smith.

The Prison Service insisted: “There is no proof this recording was made by Hamza and no evidence it was made in prison.”

But Internet terror expert Neil Doyle said: “I have spent hours listening to Hamza recordings. I am 1,000 per cent sure it is him.” (ANI)
